Jump to P-type semiconductors - P-type semiconductors are created by doping an intrinsic semiconductor with an electron acceptor element during manufacture. In p-type semiconductors, holes are the majority carriers and electrons are the minority carriers. A common p-type dopant for silicon is boron or gallium.‎Conduction in · ‎Semiconductor doping · ‎The two types of · ‎Use of extrinsic. N and P-type Semiconductors. Neither pure silicon(Si) nor germanium(Ge) are great conductors. They form a crystal lattice by having each atom share all of its 4. The term n-type comes from the negative charge of the electron. In n-type semiconductors, electrons are the majority carriers and holes are the minority carriers. N-type semiconductors are created by doping an intrinsic semiconductor with donor impurities. A common dopant for n-type silicon is phosphorus or is an n-type semiconductor?

Difference between P Type and N Type Semiconductor | P Type Semiconductor vs N Type Semiconductor

They are named as such due to the charge that they carry. Some of the other differences between P Type and N Type Semiconductors include the fact that P Type semiconductors are created by p and n type semiconductors an intrinsic semiconductor with acceptor impurities, whereas the n type is created by doping an intrinsic semiconductor with donor impurities.

The most common types of dopant for P type is boron, aluminum or gallium; whereas the most common type of dopant for N type is phosphorus, antimony and arsenic. The p-type semiconductors have a larger hole concentration than electron concentration, whereas the n-type semiconductors have a larger electron concentration than p and n type semiconductors concentration.

Additionally, in an n-type semiconductor, the Fermi level is greater than that of the intrinsic semiconductor.

In this case, the impurity adds five valence electrons to the lattice where it can only hold four. This means that there is now one excess electron in the lattice see figure below.

Note p and n type semiconductors the material remains electrically neutral. A semiconductor doped with a donor.

Because it donates an electron, a Group 5 impurity is called a donor. Note that the material remains electrically neutral.

A semiconductor doped with a donor. A free electron is now present. They "accept" electrons from the semiconductor's valence band.

This provides excess holes to the intrinsic semiconductor. Excess holes increase the hole carrier concentration p0 of the semiconductor, creating a p-type semiconductor.

Semiconductors and dopant atoms are defined by the column of the periodic table in which they fall. The column definition of the semiconductor determines how many valence electrons its atoms have and whether dopant atoms act as the semiconductor's donors or acceptors.
